LAST BLOCK PULLING DEVICE.

APPLICATION FILED NOV. 9. 1917 Patented Dec. 24, 1918.

chine of my application previously referred to;

Fig. 3 illustrates the block pulling device in juxtaposition to the instep block of a last within a shoe; and

Fig. 4 shows the gripping member after insertion in the block bore ,to release the latch and grip a block with the body of the last and shoe in the process of withdrawal from the released block.

A supporting standard 4 preferably having its upper-end 6 bent to form a bracket by means of which it may be attached to a suitable support is provided at its lower end with a bore 8. In this bore is detachably held by means of a set screw-16 or other suitable means, a stem portion 10 at the rear end of the block releasing and gripping member. This member at its forward end is split, forming spaced resilient spring arms 14 branching from an'enlargement 12 intermediate the ends of the gripping memher, which enlargement is intended to serve as a positioning stop and to engage the lower end of the standard 4.

With the block gripping member suitably supported, as suggested, the workman may grasp a shoe, such as shown in Figs. 3 and 4, in both hands, spreading apart the lacing edges of the shoe and presenting the shoe to the resilient gripping arms 14, so as to enter these arms in the bore 18 of the instep block 16 of the last. The lower edges of the arms are preferably beveled as shown,

so that as they are inserted within the block The last is bore, they will be compressed. forced upon the spring gripping arms until the latch 20 (Figs. 3 and 4) of the instep block is engaged by the end of the gripping arms and depressed to release the instep block (Fig. 4), after which the shoe with the body of the last therein is withdrawn. the instep block remaining upon the resilient arms 14 which frictionallly grip the sides of the bore With sufficient force to support,

the block and permit the shoe to be withdrawn therefrom.

The shoe with the body of the last remain ing within it, may now be presented to the machine, such "as the. last pulling. machine previously referred to, or may be subjected to any desired operation, without any attention being paid to the instep block. 11 the operation which is to be performed upon the shoe is the-pulling of the last from the shoe; the withdrawn mstep block will be found conveniently positioned for reatlasts tachment to the body of the pulled last.

Having thus described my invention. what 1.: claim as new and desire to secure by Letters Patent of the United States is 1. Means for pulling instep blocks from comprising compressible gripping arms arranged to enter the instep block hole to disengage the block latch andto hold 1,2se,45e

the released block, with a supporting standard connected to and extending from said arms.

2. Means for pulling instep blocks from lasts'comprising a standard, and con'ipressible spring arms extending from said standard and arranged to enter'the instep block hole to disengage the block latch and to hold the released block.

3. Means for pulling instep blocks from lasts comprising a standard having a socket therein, and a member detachably secured. in said socket and having spring arms normally spread apart and extending from said standard, said arms being con'ipressible to enter the instep block hole to disengage the block latch and frictionally to grip-and hold the released block.

4. Means for pulling instep blocks from lasts comprising a gripping member arranged to enter the instep block hole to disengage the block latch and constructed automatically to grip and hold the released block for separation of the block and last, and a lasts comprising a gripping member arranged to enter the instep block hole to disengage the block latch and to hold the released block upon separation of the block .and last, with a stationary support for said gripping member.

(S. A last block pulling device having a compressible gripping member arranged to enter the bore in the mstep block of a last to release the block latch and constructed, when so inserted, to be compressed and automatically to grip and hold the released block for the separation of the block and last body.

7. A last block pulling device having a gripping member arranged for insertion in the bore in the instep block of a last to rclease the block latch, said member being constructed and 'arran ed, when so inserted, automatically to grip and hold said block independently of the block latch for the separation of the'block and last body.

8. A last block pulling device having a compressible gripping member arranged for insertion in the bore ofthe instep block of a lastto release the block latch, said memher being constructed and arranged for COD]- pression by said insertion automatically and frictionally to grip and hold the released block for the separation of the block and last body.

9. A last block pulling device having a gripping member arranged for insertion in the bore of the instep block of a last to release the block latch, said member being constructed and arranged, when so inserted, automatically to grip and hold said block independently of the bloclclatch for the separation of the block and last body, and a support for said member constructed and arranged for attachment to asnitable stationary base.

10. A last block pulling (leriee having latch releasing spring arms arranged to be ('OIHPKQSSGCl by insertion in the bore of the instep block of 2'. last fr'etioimlly to grip and heitl the instep block tor the separation of the block and last body.

11. A last blovk pulling device having a latch-releasing split'fringer 0+; resilient material compressible by latch-releasing insertionin the bore in the instep block or a last frietienelly to grip and hold said instep block for the separation of the block and last body.

12. A litb'i' block releasing device comprising a standard adapted attachment to it suitable supper; and having (letneliebiy se' cured thereto a gripping n'ieinber arranged for insertion in the bore in the instep block of a last to role-use the block latch and conand last body.

1 A last block pulling device provided with eornpressible arms arranged to be fen-ed into the bore in the instep block of a last to release the block latch and frictionnlly to grip and hold the released block. 1%. A last blot-k pulling; derive provided with e spiit finger of resilient material having; beveled enils and arranged to be forcetl into the bore in the instep lilocko't a last to release the bled; latch and coincidentally to compress szricl sglit finger friction-rill; to grip and hold the releasetl block.

in testimony whereof I have signed my name to this specification.
